Title: Image coder
Inventor: ETO YOSHIRO
IPC: H04B1/66
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To reduce the processing time for entire coding by adopting the configuration such that a state value from an arithmetic coding circuit is written in a state value memory while an address designation state in the case of outputting a state value in response to a context is stored to cope with arithmetic coding of picture elements to be coded succeedingly. SOLUTION: Data of line memories 2-4 are fed to a context generating circuit 5, in which peripheral picture elements around a coded picture element are selected and stored in addresses of an ST RAM 6 being a state value memory storing a state value of a next stage as a context. Then an address of the state value memory 6 is designated by the context from the context generating circuit 25 to write the state value from an arithmetic coding circuit 9 to the state value memory 6 while the address designating state is stored in the case that the state value in response to the context is outputted to cope with arithmetic coding of picture elements to be coded succeedingly.
